Syria's Ambassador to Russia Riad Haddad said that since Russia has begun its military operation in the country, around 40 percent of ISIL infrastructures in Syria have been destroyed.

"According to our data, about 40 percent (was destroyed). In addition, a lot of terrorists have been killed. Now, they are retreating toward the Turkish border, as this country has traditionally provided them with protection," Haddad said on Wednesday.

Moscow began its military campaign against terrorists in Syria on September 30 upon a request from the Damascus government, shortly after the upper house of the Russian parliament gave Putin the mandate to use military force in Syria; FNA reported.
